The safest way to remove packages is from the command line. Syntax is "removepkg name_of_package" (as root, of course). Example: "removepkg firefox" will remove all files from the Mozilla Firefox package but nothing else.

To get the package name correct, I'd recommend using gslapt to find the exact spelling first. There may be numbers and/or upper case letters involved. You can also search /var/log/packages for that information. The package names contain additional information such as architecture and version numbers. You don't need to type all that in, just the base name of the package.

It's safe to remove top level applications which have menu entries. But there are thousands of files in a workstation install, and they work together. A specific application may need numerous supporting programs to function properly. Unless you know very well what you are doing, do not remove programs that don't show up on the menu.

One more note on gslapt: It is also used for upgrades. When you open it, click the "Update" button. Then search for your application. You may see a newer version available. Click on the square to the left of the name and select the Upgrade option.

It looks like there is no application associated to any mime type, if i try to open any file from pcmanfm-mod or spacefm (even installed pcmanfm) the "Choose Application" Dialog is displayed, and the "Recommended Applications" list is empty, i guess i could associate an application to every file-type but it takes time, and i will probably use VL7-Light in at least 4 computers (maybe 7), i don't want to do it that many times and i'm very interested in the Light configuration with spacefm.

By the way, i tested the three file managers (pcmanfm-mod, spacefm and pcmanfm) in a MEDIUM IceWM install, and the three had associated programs to the file types i tried.

is there a way to associate programs to file types automagically?

except for this, everything is running perfectly, i'm installing some programs and testing, will give feedback if something goes wrong.
